Gladiator 1933314177 QR40-ST 245/70R17.5 All-Season Commercial Truck Tire

The Gladiator QR40-ST is an all-position commercial tire designed for steer axle applications in highway service. This highway terrain, all-season tire is manufactured specifically for commercial vehicles and excels on the steer axle.

Key Features:

• Steel belt construction enhances stability, toughness, and promotes uniform wear for extended service life
• Five-rib tread design with dense siping fights irregular wear patterns
• Versatile all-season compound with symmetric tread design maximizes traction in wet, dry, and winter conditions
• Four circumferential grooves effectively disperse water, slush, and snow to prevent hydroplaning
• Closed shoulders resist uneven wear for longer tread life
• Specialized tread compound resists cuts, chips, punctures, and uneven wear
• Designed for multiple retread cycles

This tire is an excellent choice for regional or long-haul trucks, and works well on medium-duty box trucks, wreckers, and similar commercial applications. The shoulder and tread pitch are tuned to minimize road noise, while the flat, densely siped tread footprint maximizes surface contact to boost driving stability and steering responsiveness.
